lucene利用BooleanQuery进行多个Query组合查询

lucene3.0中BooleanQuery 实现与或的复合搜索 . 
BooleanClause用于表示布尔查询子句关系的类，包括：BooleanClause.Occur.MUST，BooleanClause.Occur.MUST_NOT，BooleanClause.Occur.SHOULD。必须包含,不能包含,可以包含三种.有以下6种组合： 
1．MUST和MUST：取得连个查询子句的交集。 
2．MUST和MUST_NOT：表示查询结果中不能包含MUST_NOT所对应得查询子句的检索结果。 
3．SHOULD与MUST_NOT：连用时，功能同MUST和MUST_NOT。 
4．SHOULD与MUST连用时，结果为MUST子句的检索结果,但是SHOULD可影响排序。 
5．SHOULD与SHOULD：表示“或”关系，最终检索结果为所有检索子句的并集。 

6．MUST_NOT和MUST_NOT：无意义，检索无结果。
